A universal battery charger having an adjustable pocket for receiving batteries having differing dimensions. Each battery, regardless of their differing dimensions, may be firmly supported within the adjustable pocket and receive an electrical charge from a single set of electrical contacts exposed in the adjustable pocket. The adjustable pocket is adjustable, because a battery guide of the charger includes first and second ends that alternately protrude through the plane of the housing, thus providing different dynamic supporting walls for different batteries. The adjustable pocket may accommodate different batteries by utilizing different receiving areas of the pocket. One receiving area may supports one side of a first battery with a first dynamic wall and supports other sides of the first battery with stationary walls. Likewise, another receiving area may support one side of a second battery with a second dynamic wall and supports other sides of the second battery with stationary walls.

Battery housing

Described is a two-part housing for a battery cell having circuitry separate from the main body of the cell. Finger joints, blind dado joints, and edge joints with rabbeted edges are disposed in the mating region between the two halves of the housing. An insulating and alignment wall is integral with one half of the housing, and fits in the channel between the main body of the cell and the circuitry. The housing is dimensionally stable, provides mechanical protection for the delicate cell circuitry, and the two halves of the housing may be secured using only a label wrap.

High capacity battery

Described is an integral electrical contact block and printed circuit board for an electrical device. The electrical contacts arch over components on the printed circuit board and are secured to the printed circuit board at either end of the arch. A second arch is above the lower arch, secured to the lower arch at one end, forming a structure with an open mouth. This open mouth can capture a plastic housing. The contact provides protection for components beneath it, provides for efficient use of space in an electrical device, and the mouth of the contact absorbs shock that otherwise might be transmitted directly to solder joints on the printed circuit board.
